SPECIFICATION formingpart of Letters Patent No. 772,314, dated October 1-1, 1904.

Application filed April 7, 1902. Serial No. 101,646. (No model.)

To all whom it may concern:

Be it known that I, IvER'r LARSEN, of Ohicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Hames; and I do hereby declare that the following is afull, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

This invention relates to improvements in adjustable hames for horse-collars, and refers more specifically to improvements designed to permit of longitudinal adjustment of the hames to adapt the same to collars of diiferent lengths.

Among the objects of my invention is to simplify the construction of such adjustable hames and at the same time strengthen the connections between the adjustable parts of the hames.

In the drawings, Figure 1 is a front elevation of a set of adjustable hames made in accordance with my invention, showing the same .in position on a collar on which the same are adapted to be used. Fig. 2 is a fragmentary side elevation of one of the hames, illustrating the manner of adjustably connecting the upper and lower slidably-connected parts of the hames. Fig. 3 is a longitudinal section taken on the line 3 3 of Fig. 2. Fig. 4 is a cross-section taken on line 4 L of Fig. 3. Fig. 5 is a cross-section taken on line 5 5 of Fig. 3.

As shown in the drawings, A designates a collar of that type which is separated at its lower or throat end and the side members of which are flexibly joined at the upper or wither end of the collar, whereby said side members may be separated for the purpose ofapplying the collar to and removing the same from a horse. The lower or divided ends of the collar are held or locked in place by the hames and the looking or coupling connections thereof, as will hereinafter more fully appear. Said hames consist of two similar side members, each comprising an upper tubular part or section B and a lower tubular part or section B, which are adjustably-connected by devices constituting the present invention. Said hames occupy the usual depression between the fore and aft wales of the collar and are secured to the collar in any suitable manner, as by means of loops A, conthe hames, whereby said hames may be made to fit longer or shorter collars, said connec tion is made as follows: The upper tubular member of each hamelias telescopic connection with the lower tubular member thereof, and, as herein shown, said upper member fits within the lower member. The outer telescopic member B of the telescopically-connected parts is provided with a slit 5, which extends from the extreme end thereof some distance inwardly or downwardly. O designates a clamping-sleeve which surrounds the split end of the lower section of the hames and is secured permanently thereto in any suitable manner, as by brazing. Said sleeve is longitudinally split in line with the slit 6 of the section B and is provided at each side of said split portion with laterally-directed parallel lugs O O, through which extends a clamping bolt or screw C said bolt or screw passing freely through one of the lugs and having screw-threaded engagement with the other. With this construction when the clamping bolt or screw is tightened the lugs.

are brought together, and the outer member B of the telescopic connection is contracted in close circumferential contact with the inner member B and binds said parts firmly together, so as to prevent relative endwise movement thereof.

In addition to the clamping-sleeve above de scribed for connecting said telescopic parts of the hames I have provided a supplemental clamping device which engages said parts below the clamping-sleeve and cooperates there with to make more rigid the connection between said parts. Said supplemental clamping device consists of a screw-bolt D, which extends through a suitable opening in the wall of the outer telescopic member and through a boss raised or elevated from said wall and also through an elongated slot I), formed in the inner telescopic member B. Said clamping,- screw has screw-threaded engagement at its inner end with a clamping-nut D, located within the inner tubular member and having sliding engagement therewith. The nut is made rounded or parti-cylindric on the side thereof adjacent to the bolt D and engages the inner cylindric surface of the inner tubular member of the connection. Said nut is provided on its rounded side with a raised rib (Z, which enters the slot 6 of the inner tubular member B of the telescopic connection, and said rib prevents the clamp-nut from turning or rotating in said member. Said nut is made of a width to extend entirely across the tubular section B and engages the wall of the tube opposite to the slot Z), so that when the nut is inserted into the inner tubular part of the connection it has close-fitting engagement therewith and is held always in position for connection with the clampingscrew D should said clamping-screw be entirely removed from the block. In other words, when engaged with the slot 6 the rib (Z prevents the nut from turning or rotating in said tubular section, and the bearing or contact on both sides of said tubular section prevents said rib becoming disengaged from said slot 6. The clamping-nut is cutaway at its end in the manner indicated in Fig. 5 for the purpose of lightening the same. Said nut is placed inside the tubular section B of the hames from the lower end thereof, and a stopscrew Z2 is inserted in the wall of said section in the manner shown in Fig. 3 to prevent accidental separation of said parts. The combined clamping devices shown, consisting of the clamping-sleeve C and the clamping bolt and nut D and D are not herein broadly claimed, but are made the subject of claims of an application of Robert G. Armstrong, filed of even date herewith.

An important advantage of the construction of the clamping-nut D and its relation to the inner tubular section is that said nut, together with the clamping-bolt D, aifords a very rigid clamping structure, due to the ample contact-surfaces of the nut with the inner tubular member of the connection. A further important advantage of the construction is that the nut is maintained always in position for engagement therewith of the clamping-bolt and cannot turn or rotate in a manner to throw the bolt-aperture thereof out of line with the slot 6, through which the bolt is passed to engage the same with the nut.

The hames are hinged at their upper ends by means of a pintle 6 extending through registering apertures 6 b in overlapping or crossed parts B B of said upper sections of the hames.

The lower ends of the hames are locked together by means of a locking-bolt H, which is pivoted to one of the hames and adapted to engage a locking member in a socketed casing H, attached to the lower end of the other hame. The form of coupling shown is like that illustrated in the prior United States Letters Patent to Robert G. Armstrong, issued February 26, 1896, No. 555,279, and need not be herein further described.

It is obvious that many changes in the structural details may be made without departing from the spirit of my invention, and I do not wish. to be limited to the specific details except as hereinafter made the subject of specific claims.

I claim as my invention 1.
